背景：认知领域和气味识别之间的关联是建立良好的，但社会人口变量如何影响这些relationships is less clearly.Purpose：使用调查适应蒙特利尔认知评估工具（MoCA-SA），我们评估如何年龄，性别，种族和教育塑造these relationships.Methods：我们首先使用聚类分析和多维缩放经验得出不同的认知领域从MoCA-SA，因为它是不清楚的MoCA-SA是否可以分解成认知域。然后，我们使用有序逻辑回归来测试这些经验得出的认知域是否与气味识别和社会人口学变量如何修改这些relationships.Study Population：Nationally representative sample of community dwelling US elderly adults.Results：我们确定了5的6个理论认知域，与语言域无法确定。气味识别与情景记忆、视觉空间能力和执行功能有关。社会人口变量的分层分析表明，一些认知领域和气味识别之间的关联不同的年龄，性别，或种族，但不是由education.Conclusions：这些结果表明，（1）的MoCA-SA可用于识别认知领域的调查研究和（2）性能的嗅觉测试作为一个筛选认知能力下降可能是潜在的弱在某些亚群。
Background:The associations between cognitive domains and odor identification are well established, but how sociodemographic variables affect these relationships is less clear.Purpose:Using the survey-adapted Montreal Cognitive Assessment instrument (MoCA-SA), we assess how age, sex, race, and education shape these relationships.Methods:We first used cluster analysis and multidimensional scaling to empirically derive distinct cognitive domains from the MoCA-SA as it is unclear whether the MoCA-SA can be disaggregated into cognitive domains. We then used ordinal logistic regression to test whether these empirically derived cognitive domains were associated with odor identification and how sociodemographic variables modified these relationships.Study Population:Nationally representative sample of community-dwelling US older adults.Results:We identified 5 out of the 6 theoretical cognitive domains, with the language domain unable to be identified. Odor identification was associated with episodic memory, visuospatial ability, and executive function. Stratified analyses by sociodemographic variables reveal that the associations between some of the cognitive domains and odor identification varied by age, sex, or race, but not by education.Conclusions:These results suggest that (1) the MoCA-SA can be used to identify cognitive domains in survey research and (2) the performance of smell tests as a screener for cognitive decline may potentially be weaker in certain subpopulations.
